First of all, there are more than 3 religions in this world that show your lack of knowledge in this topic.
I think just wanting those religions without mentioning other religions. Indeed, as you say it is a lack of understanding of the topic. According to my understanding, there are many great religions that exist and develop well in many countries, and a specific example is India, a country with the most religions in the world, and it is also very popular, was widely accepted.
(...)Everything is good as long as multiple religious people can coexist in this society.
And this is precisely the problem, because the nature of all dissonance stems from religious conflict and harmony seems impossible if the original nature of religions is to continue as it is. what happened over the centuries.
I am a bit more open to change in the future, when the names attached to religion will be replaced by the advancement of consciousness and there will still exist religions as our religion
"wisdom and truth", "religion of faith (will be weakened)", "religion of violence". And religions - views in society will accompany the general progress/degeneration of humanity.
